Description
Technical field
Technical field of transmission is the utility model is related to, especially a kind of sector gear.
Background technology
At present, fracture or deformation occur when the gear teeth in existing sector gear are extruded by external force in use
Phenomenon occurs, and gear-tooth strength is poor, so as to shorten the service life of sector gear.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to spend relatively strong before providing a kind of gear teeth and extended
The sector gear of service life.
What the technical solution of the utility model was realized in：A kind of sector gear, including gear, its feature exist
In：The gear includes base portion and the scallop being fixedly connected with base portion, and the outward flange of the scallop is provided with projection
Portion, the both sides of the lug boss are respectively arranged with several gear teeth, several gear teeth etc. being fixedly connected with the outward flange of scallop
Away from being arranged on the outward flange of scallop, strengthening groove is formed between the adjacent gear teeth, the groove width of the strengthening groove is from bottom land toward groove
Become larger at mouthful, and the ratio of width is 0.29 at the slot bottom width of strengthening groove and the notch of strengthening groove.
Preferably：The top of several gear teeth is plane.
By using above-mentioned technical proposal, form strengthening groove between the adjacent gear teeth, the groove width of strengthening groove from bottom land toward
Become larger at notch, and the ratio of width is 0.29 at the slot bottom width of strengthening groove and the notch of strengthening groove, the gear teeth are by outer
Power is not in phenomenon of rupture when extruding, and gear-tooth strength is stronger, so as to extend the service life of sector gear；If plus
When the ratio of width is more than 0.29 at the strong slot bottom width of groove and the notch of strengthening groove, occur when the gear teeth are extruded by external force disconnected
Phenomenon is split, gear-tooth strength is poor, so as to shorten the service life of sector gear；If the slot bottom width of strengthening groove is with adding
When the ratio of width is less than 0.29 at the notch of strong groove, occur metaboly when the gear teeth are extruded by external force, the gear teeth are strong
Spend it is poor, so as to shorten the service life of sector gear；So width at the slot bottom width of strengthening groove and the notch of strengthening groove
Ratio be 0.29 relatively reasonable, be not in that fracture or metaboly occur when the gear teeth are extruded by external force, gear-tooth strength compared with
By force, so as to extending the service life of sector gear.
The utility model is further arranged to：
By using above-mentioned technical proposal, the bulk strength of scallop is enhanced, so as to be effectively guaranteed sector gear
Service life.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model embodiment structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in figure 1, the utility model discloses a kind of sector gear, including gear, it is specific in the utility model
In embodiment, the gear includes base portion 1 and the scallop 2 being fixedly connected with base portion 1, the outward flange of the scallop 2
Lug boss 3 is provided with, the both sides of the lug boss 3 are respectively arranged with several gear teeth being fixedly connected with the outward flange of scallop 2
4, several gear teeth 4 are placed equidistant, on the outward flange of scallop, strengthening groove 5, the strengthening groove being formed between the adjacent gear teeth 4
5 groove width from bottom land toward notch at become larger, and H2 width at the notch of the slot bottom width H1 of strengthening groove 5 and strengthening groove 5
Ratio is 0.29.
In the utility model specific embodiment, the top of several gear teeth 4 is plane.
By using above-mentioned technical proposal, form strengthening groove between the adjacent gear teeth, the groove width of strengthening groove from bottom land toward
Become larger at notch, and the ratio of width is 0.29 at the slot bottom width of strengthening groove and the notch of strengthening groove, the gear teeth are by outer
Power is not in phenomenon of rupture when extruding, and gear-tooth strength is stronger, so as to extend the service life of sector gear；If plus
When the ratio of width is more than 0.29 at the strong slot bottom width of groove and the notch of strengthening groove, occur when the gear teeth are extruded by external force disconnected
Phenomenon is split, gear-tooth strength is poor, so as to shorten the service life of sector gear；If the slot bottom width of strengthening groove is with adding
When the ratio of width is less than 0.29 at the notch of strong groove, occur metaboly when the gear teeth are extruded by external force, the gear teeth are strong
Spend it is poor, so as to shorten the service life of sector gear；So width at the slot bottom width of strengthening groove and the notch of strengthening groove
Ratio be 0.29 relatively reasonable, be not in that fracture or metaboly occur when the gear teeth are extruded by external force, gear-tooth strength compared with
By force, so as to extending the service life of sector gear.
In the utility model specific embodiment, the scallop 2 includes the first rib 21 and second being sequentially connected
Rib 22, the junction of the rib 22 of the first rib 21 and second are provided with arc and strengthen groove 23, and the arc adds
Strong groove 23 includes the first curved portions 24 and the second curved portions 25 being sequentially connected, and the radian of first curved portions 24 is more than the second arc
The radian in shape portion 25.
By using above-mentioned technical proposal, the bulk strength of scallop is enhanced, so as to be effectively guaranteed sector gear
Service life.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
